These ZnO-Lip show an unprecedented ability to assist cavitation, which is reflected in enhanced sonoluminescent light emission with respect to the pristine nanocrystals or the pure water. Highly defined and sharp sonoluminescent images of cultured cells are indeed obtained, for the first time, when ZnO-Lip are used. Furthermore, ZnO-Lip were adopted as a nanosized agent for contrast-enhanced ultrasound imaging, i.e. echography, first in solutions, and then on ex-vivo tissues. A prolonged over time and bright imaging effect is observed when adopting the developed nanoparticles. Furthermore, their nanometric size and potential targeting with biomolecules would allow ease extravasation and tissue or even cell penetration, achieving enhanced-contrast imaging.

The results showed that the optimal extraction process of ultrasound-assisted enzyme method was 102 min ultrasonic extraction time, 48 °C extraction temperature, 1:80 material-liquid ratio, and 1600 U/g enzyme additions. The predicted polysaccharide yield was 29.64 %, and the actual polysaccharide yield was 29.71 ± 0.31 %.

It mitigates damage to the thymus and spleen tissues, increases white blood cell counts, regulates the ratio of T lymphocytes and the levels of related factors, enhances macrophage phagocytic function to improve nonspecific immune responses, and boosts the levels of immunoglobulins IgA and IgG to enhance specific immune function.

Addition of the A- and B-subunits before and after ultrasonic minimally affected SLP secondary structure. A-subunit addition before ultrasonic negligibly affected SLP tertiary structure. Addition of the B-subunit after ultrasonic reduced hydrophobic thermal aggregation. However, the small B-subunit size was unfavorable for the formation of a gel matrix, which led to poor gel properties.

Endogenous fluorescence spectroscopy demonstrated increased protein unfolding after ultrasonic and decreased disulfide bonds. These changes improved the gel state. Rheological and microstructural analyses revealed increased energy storage modulus and yield strain, accompanied by a more homogeneous microstructure following ultrasonic. Microscopic improvement resulted in increased encapsulated water within interstitial spaces of the A-SLP gel matrix. This enhanced water mobility in B-SLP gels, in turn weakening gel stability. The changes observed in B-SLP were primarily due to reduced hydrophobic interactions between the proteins.
